Problems solved by technology

Existing whitening washing powder needs higher washing temperature and longer washing time when washing clothes, which not only wastes energy but also affects the service life of fabrics after long-term high-temperature washing
Even so, the backwash rate of the fabric is still high, and the whiteness decreases after multiple washings

Abstract

The invention discloses an industrial low-temperature whitening washing powder, which is prepared from the following components according to a certain proportion: powdery pentahydrate sodium metasilicate, sodium carboxymethylcellulose, sodium nitrilotriacetic acid, lipase, amylase, protease, fluorescent agent, fatty alcohol-polyoxyethylene ether, amphoteric imidazoline, triclosan disinfectant, sodium perborate monohydrate, non-phosphorous additive and fatty acid potassium. The preparation method of the brightened goods washing detergent comprises the steps of firstly putting the weighted powdery pentahydrate sodium metasilicate, sodium perborate monohydrate, fatty acid potassium and sodium carboxymethylcellulose into a stirring kettle through a filter screen for 10 minutes; while stirring, simultaneously adding the non-phosphorous additive to the stirring kettle for three times, and continuously stirring for 3 minutes; pre-stirring the triclosan disinfectant, the amphoteric imidazoline and the fatty alcohol-polyoxyethylene ether for 4 minutes, and adding thetriclosan disinfectant, the amphoteric imidazoline and the fatty alcohol-polyoxyethylene ether to the stirring kettle for stirring for 4 minutes; adding the sodium carboxymethylcellulose to the stirring kettle through the filter screen for stirring for 5 minutes; uniformly scattering the lipase, the amylase and the protease into the stirring kettle for stirring for 3 minutes; and finally putting the fluorescent agent into the stirring kettle for stirring for 4 minutes.

Description

Technical field: [0001] The invention relates to an industrial washing powder, in particular to an industrial low-temperature whitening washing powder which can reduce the temperature of washing water, save energy, improve the whitening effect and prolong the service life of fabrics. Background technique: [0002] The main task of the hotel laundry room is to wash all kinds of fabrics such as towels, bed sheets, quilt covers, uniforms, and employee uniforms. The washed fabrics should meet the requirements of no stubborn stains, clean and tidy, maintain or increase whiteness, and low return washing rate, etc. For this reason, whitening detergent must be used when washing. Existing whitening washing powder needs higher washing temperature and longer washing time when washing clothes, which not only wastes energy but also affects the service life of fabrics after long-term high-temperature washing. Even so, the backwash rate of the fabric is still high, and the whiteness decre...
